The megabat family contains the largest bat species, with individuals of some species weighing up to 1.45 kg (3.2 lb) and having wingspans up to 1.7 m (5.6 ft). Not all megabats are large-bodied; nearly a third of all species weigh less than 50 g (1.8 oz).
The hammer-headed bat (Hypsignathus monstrosus), also known as hammer-headed fruit bat, big-lipped bat, and hammerhead bat, [2] [3] is a megabat widely distributed in West and Central Africa. It is the only member of the genus Hypsignathus , which is part of the tribe Epomophorini along with four other genera.
Fruit bats, also known as flying foxes or megabats, are the 197 species of bats that make up the suborder Megachiroptera, found throughout the tropics of Africa, Asia, and Oceania, of which 186 are extant. The suborder is part of the order Chiroptera (bats), and contains a single family, Pteropodidae.
The large flying fox (Pteropus vampyrus, formerly Pteropus giganteus), also known as the greater flying fox, Malayan flying fox, Malaysian flying fox, large fruit bat, kalang, or kalong, is a southeast Asian species of megabat in the family Pteropodidae. [3]
It forms harmonious mixed species colonies with another megabat, the large flying fox (Pteropus vampyrus). [21] When time to leave the roosts for nightly foraging, the two species will head in the same direction. [21] In the 1920s, colonies of these two species would number as many as 120,000 individuals.
Spotted-winged fruit bats are unusually small megabats, with a head-body length of 5.2 to 6.2 centimetres (2.0 to 2.4 in), [2] a wingspan of 28 centimetres (11 in), and an adult body weight of around 13 grams (0.46 oz). Most of the head and body are covered in thick blackish-brown fur, while the underparts are a pale grey-brown.
The Egyptian fruit bat is among the few megabats using echolocation. Although it is considered a primitive form compared to non-megabat species, [3] [29] this has been questioned. [30] A few other megabat species echolocate via creating clicks with their wings. [29]
The grey-headed flying fox (Pteropus poliocephalus) is a megabat native to Australia. [3] The species shares mainland Australia with three other members of the genus Pteropus: the little red P. scapulatus, spectacled P. conspicillatus, and the black P. alecto.
